Be it known that I, EDCAHD Ri'moeen, a

eith'en of theRepublie of Switzerland, re-

siding p t Zurich,- Switzerland, heve invented 'hew and useful Improvements in Devices for the Gas-Tight Smiling of-the Cover of a .--iiig tohe'e. fullielear, and exact descriptioh of the invention; such as will enable others skilled in the art; to which it upper-wins to "make and use the same, reference heing had to the accompnnyingdmwing, and to lei'ters or figures of reference marked thereon,'

which form a pert of-this Specification.

' prbcessesnnd'deviees for-the gas-tight seal- The invention relates to improvements in mg 0f the cover of avessel. According to l same theproeess'consists in milking a metal wire into a tapered joint formed. between the wall of a vessel and its cover which is .to

' be made" ae'tiglmnnd in filling the space outside 0 tlllS 'metal wire with solder.

The .device provides in joint. formed by the wall of a vessel and its covet-,- the form f of the pier part; of'the cross-sedi ion of.

lieingitapered toward the inside of thevessol, a ne'taI).wire cnlkedinto-the so formed upper part of the joint the space, outside of this metal wire being filled with solder. I

A clearer: unrlerstamling of what is included in this improvement may be obtained by reference to the annexed drawing sheet, where in Figure 1 ie shown the {flliSR-{sfiCtiOli through-n vessel l whichis to-beeealecl by means of. cove 2.

In Fig. 2 the connection and. the packing between body and-cover is shown to nlm'ger First, the cover 2; is serewecl'jdown to-therim ef tho-reesel 1., by nae-en's of thread 3, till it firemen-shoulder 4:. The thread 3' extemls only on the lower linlf of the coverliim. Ahovethe thread-3 the tapered groove 5, which narrows towarc the interior of the vessel, is' drnied thrfou h the fit'tinto:

In testimony that I cleimthe foregoing as my invention I have signed my n' e in presence of two subscribing witnesses.
